scikit-learn accuracy_score: Usage and When It Misleads

scikit-learn accuracy_score: the Command Prompt showing a model scoring 98 percent accuracy while catching none of the fraud cases

The accuracy_score in sklearn returns the fraction of predictions that match the truth. Here’s the import and the whole call: It takes the true labels first and the predictions second. Swapping them gives the same number, so the mistake hides, but every other metric in sklearn.metrics cares about the order. Everything here ran on scikit-learn … Read more >>
